I know I can create a parameter in the C file itself and use it in
assembly(this is what sdcc generates), I want to know about the internal
registers of the 8051. Can I use any?

Mobile security can be enabling, not merely restricting. Employees who
bring their own devices (BYOD) to work are irked by the imposition of MDM
restrictions. Mobile Device Manager Plus allows you to control only the
apps on BYO-devices by containerizing them, leaving personal data untouched!
